That's amazing fun -- If you're in YouTube, check out the 80 or so posts for coloradohomemovies -- Back in the '80's, blue screen/green screen effects involved machines costing hundreds of thousands of dollars. We only were able to use ours because someone donated an older $200,000.00 setup to the station. Check up the windup monster toys in the background on "Live From Monster Island", or the cheesy street scenes in "Crusin' Live From Longmont", etc. etc. Yeah, we put it to good use . . . of course, we used it to create disembodied talking heads, invisible doors, flying effects, etc. etc. -- any cheesy thing you could think of using it for, we did. peter johnson/denny crane

The thing I have always found most difficult with chromakey is controlling "spill"... it shows up everywhere, faint green reflections in people's glasses, vaguely nauseated skin color... horrible. It takes a lot of light to keep the foreground from being adversely affected.
